He and his grandson, Malachi, have multiple Pidgey that act as carrier pigeons. He is the one who started the Pidgey Express business, as a business that uses the abilities of the Pidgey in order to send packages and newspapers to the nearby islands without ferry service. For more than fifty years, he has dedicated his life to training and taking care of the Pidgey. In order to train the Pidgey, Denjirō would fly on a mini-blimp over and over again to show them the routes they had to take. He would wait up on stormy nights until every Pidgey returned and wait with them until they fell asleep if they were lonely. Because of this dedication, he was not able to attend his son's wedding or his grandson's birth. That is why Denjirō planned on retiring the business once he retired, so that Malachi wouldn't miss the important things in life like he had.

During Carrying On!, the Pidgey were the target of a Team Rocket heist, literally being plucked from the sky. Malachi went and saved the Pidgey for his grandfather. This impressed Denjirō so much that he changed his mind about retiring the business, and helped his grandson become a professional Pidgey Express Man.

Pidgey (multiple)

Denjirō has many carrier Pidgey that he and his grandson Malachi own. They are used in the Pidgey Express business to send packages and newspapers around the nearby islands. In Carrying On, the Pidgey were seen flying around and delivering messages. They were seen in Denjirō's house, and many were later captured by Team Rocket. But with the help of Malachi's favorite Pidgey, Ken, and Ash's Noctowl, the Pidgey were freed and Team Rocket was sent blasting off.
